- Appearance
- Bats are brown with a l belly, with hairs dark at base; wings and interfemoral membrane black. Their colors vary from light in deserts to dark in forests. Length is 110-130 mm; weight is 13-18 g. No fur on wings or interfemoral membrane.
- Habit
- Some bats prefer to roost in barns, attics, caves or abandoned mines, those shelters providing safety from predators, protection from fluctuations in weather, and seclusion for rearing the young. Other species select hollow trees or rock crevices as their daytime resting site, while certain ones are known to roost in exposed locations, clinging to tree trunks or hanging upside down from tree branches.
- Diet
- Although various bat species eat different kinds of food, the vast majority consume a variety of insects such as moths, beetles, gnats, and crickets.
- Reproduction
- Most bats have a breeding season, which is in the spring for species living in a temperate climate. Bats may have one to three litters in a season, depending on the species and on environmental conditions such as the availability of food and roost sites.
